Object doesn't support property or method 'querySelector' in IE 10

Question

I encounter a problem with IE 10 regarding its support. The website is very good to use in other browser except IE.. I also tried using IE 11 and still it didn\'t work.

Answer 1

IE Developer Tools [F12] was useful for me in diagnosing this (IE11):

• the toolbar on dev tools has a dropdown that lets you select IE compatibility version
• set the desired version using the dropdown on the toolbar, then refresh the page
• in my case the error went away when using version 8 or greater

To fix the issue, I ended up adding a meta tag as described here. (I actually added it via the web.config as shown here).
